Fireproof armored medium-voltage power cable

The utility model discloses a fireproof armored medium-voltage power cable, which comprises a cable core consisting of a plurality of conductive wire cores, each conductive wire core comprises a conductor, and an insulating layer, a flame-retardant layer, a shielding layer and a sleeve are sequentially arranged outside the conductor; gaps among the plurality of conductive wire cores are filled with an intumescent flame retardant layer; the outer side of the cable core is wrapped with an oxygen blocking layer, and the oxygen blocking layer is sequentially wrapped with a waterproof layer, an inner sheath, an armor layer and a flame-retardant outer sheath. According to the cable, the gaps among the plurality of conductive wire cores are filled with the intumescent flame retardant layers, andthe intumescent flame retardant layers form a porous foam carbon layer in a condensed phase during high-temperature combustion, so that fireproof and flame-retardant effects are achieved; due to the design of the oxygen barri
